fsh (fowl shell)

This is a learning project with the goal of building a small shell in Rust (based on the codecrafters challenge).

Features

• Basic REPL (Read-Eval-Print-Loop) with command execution (built-in and path), argument handling (separation by whitespace only)
• Supported built-in commands:
  • echo
  • exit
  • type
  • pwd

Roadmap

• Additional built-in commands like cd, and history
• Quoting & escaping (single & double quotes, backslash escaping)
• I/O redirection (stdout, stderr)
• Pipelines (built-in and multi-command pipelines)
• Autocompletion (built-in, external, path)
• History (list, execute from history, arrow navigation) & history persistence

Installation

You can either download a binary from the releases page or build it from source (requires cargo / rust):

git clone https://github.com/fowl-ow/fsh.git
cd fsh
cargo install --path .

Development Setup

Development requires Rust.

Add git hooks:

git config core.hooksPath .githooks
